“…On the contrary, if DS content is less than 30%, the absorption is not affected. In the same way, Tebbal and Rahmouni (2016) have shown the positive impact of partial replacement of DS by CS (combination of 1/3 DS with 2/3 CS) in High-performance concrete (HPC) concrete, which leads to improve the mechanical strength of concrete immersed in aggressive environment. Mortars and concretes made with DS are more porous than those made with RS, which facilitates the penetration of aggressive chemical solutions and leads to reduce the grip properties and mechanical characteristics of concretes.…”

Purpose The purpose of this study is to contribute with experimental study of the effects of binary and ternary combinations of river sand (RS), crushed sand (CS) and dune sand (DS) on the physical and mechanical performances of self-compacting concrete (SCC) subjected to acidic curing environments, HCl and H2SO4 solutions. Design/methodology/approach Five SCCs were prepared with the combinations 100% RS, 0.8RS + 0.2CS, 0.6RS + 0.2CS + 0.2DS, 0.6RS + 0.4DS and 0.6CS + 0.4DS. The porosity of sand, fluidity, deformability, stability, compressive strength and sorptivity coefficient were tested. SCCs cubic specimens with a side length of 10 cm were submerged in HCl and H2SO4 acids, wherein the concentration was 5%, for periods of 28, 90 and 180 days. The resistance to acid attack was evaluated by visual examination, mass loss and compressive strength loss. Findings The results showed that it is possible to partially substitute the RS with CS and DS in the SCC, without strongly affecting the fluidity, deformability, stability, compressive strength and durability against HCl and H2SO4 attack. The two combinations, 0.8RS + 0.2CS and 0.6RS + 0.2CS + 0.2DS, improved the compactness and the resistance to acid attacks of SCC. Consequently, the improvement in SCC compactness, by the combination of RS, CS and DS, decreased the sorptivity coefficient of SCC and increased its resistance to acid attacks, in comparison with that made only by RS. Originality/value The use of RS is experiencing a considerable increase in line with the development of the country. To satisfy this demand, it is necessary to substitute this sand with other materials more abundant. The use of locally available materials is a very effective way to protect the environment, improve the physico-mechanical properties and durability of SCC and it can be a beneficial economical alternative. Few studies have addressed the effect of the binary and ternary combination of RS, CS and DS on the resistance to acid attacks of SCC.

“…al.14 developed set of coefficients to address the issue with respect to workability of concrete. Several other studies report use of waste products as replacement of the ingredients of concrete for example demolishing waste as replacement of fine and coarse aggregates 15 , local sand 16 , metallurgical sludge waste as coarse aggregates 17 , improved recycled aggregates by removing impurities using air blower 18 . From the above discussion it may be observed that either the literature is silent or least work is devoted on studying the effect of type of sand on workability and compressive strength of concrete made with recycled aggregates from demolishing waste.…”

The ever-increasing need of infrastructure around the globe gave rise to consumption of concrete ingredients at faster pace and generates huge quantum of the construction and demolishing waste. Both factors are serious problem to environment and waste management. Therefore, this research article presents the laboratory investigation on the effect of type of fine aggregates in recycled aggregate concrete prepared with recycled aggregates from demolished concrete. It will not only reduce the waste management to some extent, help in preserving the environment, avoid health problems of inhabitants, but also help in preserving the conventional sources of aggregates. Three types of fine aggregates, i.e. river sand, pit sand and hill sand are used. The concrete using 1:2:4 mix and 0.5 water cement ratio is designed in two groups. First group used only conventional aggregates whereas, in second group 50% recycled aggregates from demolished concrete are used. In each group three batches using river sand, pit sand and hill sand are used. Slump test of each batch is conducted. In each batch 5 cylinders of standard size are prepared, cured for 28-days and tested for compressive strength. Obtained results showed better performance of conventional concrete with river sand but the induction of recycled aggregates affected both workability and compressive strength. The workability of recycled aggregate concrete with river sand was better (-14%) compared to concrete with hill sand (-20%). However, slump values for all batches remained within limits specified for normal concrete. Use of hill sand in recycled aggregate concrete showed better performance in terms of compressive strength as the residual compressive strength was recorded equal to 86% in comparison to conventional concrete with river sand. Keywords: Recycled aggregate concrete, workability, compressive strength, type of sand, fine aggregates, demolishing waste, green concrete..

“…The X-ray diffraction (XRD) results also indicated that the Ca(OH) 2 peak showed a high density in the concrete without additives and completely disappeared with the presence of silica fume and slag. Moreover, the peak intensity of C 4 AH 13 sharply recorded with silica fume and granular slag (Tebbal and Rahmouni, 2016). Behim et al (2002) also claimed in their research that the size of crystallization and particle size of the slag plays an important role in the potential development of the mechanical resistance of the mortar, as the grinding has two factors: smoothness and also the surface stimulation through the creation of defects.…”

Purpose This paper aims to express a mathematical model that predicts the effect of mineral additives on the physical–mechanical properties of high-performance sand concrete (HPSC), using SAS's JMP7 statistical analysis software. Design/methodology/approach A mixture design modeling approach is applied to sand concrete (SC) for optimizing mixtures without being obliged to do a lot of experiments, where the cement is partially replaced with two mineral additives silica fume (SF) and blast furnace slag (BFS) in proportions as high as 20% of the mass. A total of 15 mixtures of sand concrete is prepared in the laboratory using this analytical technique in combinations with binary and ternary systems to estimate the workability and the compressive strength (CS) of sand concrete at 7 and 28 days. Findings The results obtained showed that the use of derived models based on the experimental design approach greatly assisted in understanding the interactions between the various parameters of the studied mixtures; the mathematical models present excellent correlation coefficients (R² = 0.96 for CS7 days, R² = 0.93 for CS28 days and R² = 0.95 for slump) for all studied responses. Moreover, it was also found that the inclusion of additives (SF and BFS) in binary mixture SC12 and ternary mixtures SC8 leads to a significant improvement in mechanical strength compared to reference sand concrete SC15. These results give the possibility to obtain a formulation of HPSC. Originality/value This paper shows the possibility of manufacturing high-performance sand-concrete with good compressive strength; the developed mathematical model by using SAS's JMP7 statistical analysis software allowed us to reach a strength compression value of about 60 MPa, in 28 days, by replacing 10% of the cement weight with silica fume. Furthermore, with partial replacement of the cement weight (15%) with two additions such as silica fume (10%) and blast furnace slag (5%), a 58 MPa of compressive strength can be achieved, without overlooking the fact that this can be a key economic and environmental alternative.
